On the plus side these VCR's were constructed in a modular fashion with each
printed circuit board carrying out a distinct function. On the down side,
these many PCB are connected together using plugs, sockets and wire links
which are prone to failure. The electronics inside the VCR's is by todays
standard fairly straight forward with many discrete componenets being used
together to perform the complex functions required. This means getting
hold of components to repair electrical problems is by and large still
possible. However this good news is more than wiped out by the fact that
it is now near impossible to get hold of mechanical parts such as pressure
rollers, capstan motors and video heads. For the most part it is a case of
having to break up several machines to get one working.
Like most V2000 models this VCR suffered from problems associated with
dry solder joints. Before carrying out anything else it is advisable
to check the PCBs for dry joints. In particular the power supply section
and it's linear regulators should be checked.
Also prone to failire
were the drive circuits for the video head actuators.
These supplied high voltages to activate the piezo-electric actuators
and as such were under stress most of the time. A good maintainance
procedure is to replace all the capacitors in this part of the VCR and
to resolder all joints.
Video Heads If the VCR suffers from
mistracking first check the voltage drive to the piezo-electric crystals
used in the Dynamic Tracking circuits. Video heads for V2000 machines
are now rare and extremely difficult to obtain.
